Debugging issues in DPDK applications running in production might be troublesome. Core dumps and sufficient logging can provide some insight, but finding root causes of application issues can be hard. Attaching debuggers to running applications can be sometimes unacceptable, because of application’s possible downtime. rr is a recording debugger, developed by Mozilla Foundation, which allows developers to record a trace of running application and debug it offline. This talk explores the possibility of using rr to troubleshoot issues with DPDK applications, steps required to use it in DPDK ecosystem and possible performance impact.
